On base blocks fitted with reserve plates, seal work connec
tions (2 or 4) with blanking plugs or threaded blanking plugs
to protect them from dirt.
In order to guarantee the optimum efficiency of the CPA−SC
valve terminal, we recommend that the supply air tubing and
the exhaust air tubing be connected on both sides in the
following cases:
when large volume cylinders are operated at high speed
when several valves are switched simultaneously to flow.
Please note
Valves which control large−volume actuators should be
operated in a separate pressure zone.
You will then avoid problems with backpressure in exhaust
channels 3 and 5.
3.5.1 Connecting the pneumatic tubing
Please note
·
Seal connections which are not required for the function
ing of the CPA−SC valve terminal with blanking plugs.
·
The pressure compensation hole (connection L) must not
be sealed with a blanking plug.
·
The sequence in which the work tubing is connected
depends on the screw connectors used:
Screw connector with socket head screw:
Any desired sequence is possible.
Screw connector with external socket:
Fitting should preferably be undertaken from left to right
(space for the wrench).
